Referring now to FIGS. 1 to 4, inclusive, of the drawings, the railway refrigerator car 2@ there illustrated, and embodying the features of the present invention, essentially comprises a rigid longitudinally extending underframe 2 1 that is carried by a pair of longitudinally spacedapart trucks 22 provided with flanged wheels 23 cooperating with the track rails of an associated railway track,

indicated at 24. As best shown in FIG. 4, the underframe 21 comprises a longitudinally extending center sill 25 carrying a plurality of laterally extending and longitudinally spaced-apart side trusses 26 that, in turn, carry a pair of longitudinally extending and laterally spaced-apart side sills 27, as Well as a pair of laterally extending and longitudinally spaced-apart end sills, not shown, and also a number of longitudinally extending and laterally spaced-apart stringers 28. The underfrai e 21 is o skeleton Construction and directly carries upon the top thereof a substantially horizontally disposed floor panel 30. i

More particularly, the fioor panel 30 is of composite Construction, including a plurality of cooperating sections suitably Secured together; and each of the sections of the floor panel 3%* essentially comprises an outer ply- Wood sheet 31, an inner plywood sheet 32 and an intervening or intermediate slab 33 of heat-insulating material. Preferably, the slab 33 essentially coniprises a block of foamed polystyrene having a high compressive strength; and the plywood sheets 31 and 32 are suitably cenented to the opposite surfaces of the slab 33 by intervening layers of Water-impervious cement, not shown. Accordingly, the individual sections of the floor panel 3@ may be prefabricated and then assenbled and secured together to definc the composite floor panel carried upon the top of the underframe 21.

As best shown in FIGS. 12 and 13, the floor panel 36 may be secured to each of the stringers 23 by a series of longitudinally spaced-apart bolts ZE and cooperating clips 2912. In the arrangement, an opening 31@ is ormed only through the outer plywood sheet 3 of the floor panel 30 and communicating with an aligned cavity 33:: provided in the adjacent outer surface of the polystyrene slab 33. Also the bolt 29 is provided with a thread-ed shani: and an annular oflset head 2%, so that the head 2% may be inserted through the opening 3"a provided in the outer plywood sheet 31 and into the cavity 3361 formed in the polystyrene slab 33; whereupon the shank of the bolt 29 is rotated so as to cause the head 29!) thereof to rotate in the cavity 33a and to overlap the adjacent portion of the outer plywood sheet 31 disposed immediately above the upper flange of the stringer 28. Also, the clip ?Ba is provided with an upwardly ot'iset tongue 2% that is arranged in the opening Sia, when the central hole provided in the clip 2911 is arranged on the threaded shank of the bolt 29; which tongue 290 disposed in the opening 31a prevents rotation of the clip 2%, after the cooperating nut 29d is threaded upon the shank of the bolt 29. Accordingly, in the final assembly, the upper flange of the stringer 28 and the adjacent portion of the outer plywood sheet 31 are securely clamped between the ead 2% of the bolt 29 and the clip 29@ that is secured in place upon the shank of the bolt 29 by the associated cooperating nut 29d. This arrangement' is very advantageous as it efleets positive securing of the floor panel 39 to the stringers 28, without the provision of bolts through the floor panel 30, thereby to minimize the transfer of heat froni the exterior through the floor panel 39.

The Construction and arrangement of the fast-ening device, including the bolt 29 and the clip 2%, and the particular cooperation thereof with the floor panel 36, are disclosed and claimed in the copending application of Arthur E. Nyberg, Serial No. 66,865, filed November 2, 1960.

The upper surface of the inner plywood sheet 32 of the floor panel 30 carries a main floor 34 suitably secured thereto and formed of Wood; and a plurality of longitudinally extending and laterally spaced-apart stringers 35, in the form of I-beams, are carried by the main floor 34 and suitably secured thereto. In turn, the upper flanges of the I-beams 35 carry a plurality of laterally extending and longitudinally spaced-apart boards 36 formed of Wood and suitably secured thereto; which boards 36 deflne a work-floor or lading-supporting floor upon the floor panel 30.

Further, the refrigerator car Z@ comprises a body of substantially box-like form that includes a pair of longitudinally extending and laterally spaced-apart side walls 40, a pair of laterally extending and longitudinally spacedapart end walls 41 and a roof 42, all formed of sheet steel. In the arrangement, the lower end of each of the side walls is suitably secured, as by Welding, to the adjacent outer surface of the side sill 27; and each of the side walls 48 is reinforced by a plurality of upstanding and longitudinally spaced-apart outside posts 43 suitably secured thereto, as by welding. Sniilarly, the lower end of each of the end walls 41 is suitably secured, as by welding, to the adjacent outer surface of the end sill, not shown; and each of the end walls 41 is reinforced by deep laterally extending and vertically spaced-apart corrugations formed therein. The upper end of each of the side walls 49 is pro- Vided with a substantially Z-shaped construction 44 terminating in an outwardly directed eave flange 45 that is suitably secured, as by welding, to the adjacent eave of the root sheet 42, as best shown in FIG. 4. Also, the upper ends of the two end walls 41 are brought to suitable junctions With the ends of the roof sheet 4-2 and suitably secured thereto in a manner, not shown, as by welding. Further, the central portion of the roof 42 carries a longitudinally extending catwalk 46 of any suitable Construction and for the usual purpose.

As best shown in FIGS. 2 and 6, each of the four corners of the car body is reinforced by an arrangement including an upstanding post 5@ formed of steel and a cooperating upstanding post 51 formed of Wood. Specifically, the post 50 has a substantially W-shape in lateral section and bridges together the adjacent portions of the side wall and the end wall 41, the end wall 41 wrapping around the post 50 and overlapping the adjacent end of the side wall 40. Also, the post 50 embraces two sides of the post 51 to provide a strong unitary Construction. The post 51, one wing of the post 50 and the adjacent portion of the end wall 41 are rigidly secured together by a series of Vertically spaced-apart bolts 52 extending through aligned openings therein; which bolts 52 may be formed of stainless steel in order to minimize the heat flow therethrough. As illustrated, the end of the side wall 40 is arranged between the overlapping end of the end wall 41 and the other wing of the post Sh; which assembly may be rigidly retained in place, as by welding.

An upstanding laterally extending partition 69 is arranged within the car body adjacent to the left-hand end thereof, so as to subdivide the interior of the car body in a lading compartnient 61 disposed on the right-hand side of the partition 6@ and a machinery compartment 62 disposed on the left-hand side of the partition 60, as shown in FIG. 2. In the arrangement, the lading compartment 61 is substantially larger than the machinery Compartment 62; and the partition is of composite Construction including inner and outer steel sheets 63 and 64, securedtogether in spaced-apart relation by a' plurality of upstanding I-beams 65 arranged in laterally spaced-apart relation. As indicated in FIG. 1, the opposite lower sides of the machinery compartment 62 are accessiblefrorn the exterior through cooperating doorways respectively provided in the side walls 40; which doorways are normally closed by sliding doors 66 that are respectively supported by suitable guideways 67 carried by the side walls 40 of the car body. In passing, it is mentioned that refrigerating machinery, not shown, is removably supported in the machinery eompartmcnt 62; which refrigerating machinery may be removed from the machinery compartment 62 through the doorways provided in the' side walls 46, when the doors 66 occupy their open positions. Also, the side walls 40 respectively carry ventilated panele 66' communica-ting with the opposite upper portions of the nachinery compartment 62 in order to accommodate ventilation of the refirigerating machinery disposed therein.

Further, the car body houses a heat-insulating liner that includes, in addition to the previously described floor panel 39, two side panels'7ti` and 75, and two end panels 80 and 90, and also a ceiling panel 100. The side panel 70 is arranged a'djacent the lower side Wall 40, as shown in FIG. 2, and comprises a plurality of sections suitably secured together; the side panel '70 being of composite Construction' essentially the same as that of the floor panel 30, preivously described; whereby the side panel 70 includes the outer plywood sheet 71, the inner plywood sheet '72 and the intermediate slab '73 of foamed polystyrene. The side panel '75 is arranged adjacent to the upper side wall 40, as shown in FIG. 2, and comprises a plurality' of sections suitably secured together; the side panel being of composite constrTction essentially the same as that of the floor panel 30 previously described; whereby the side panel *75 includes the outer plywood sheet '76, the inner plywood sheet 77 and the intermediate slab 78 of foamed polystyrene. The end panel &ti is arranged adjacent to the partition 6%, as shown in FIG. 3, and comprises a plurality of sections suitably Secured together; the end panel %ti being of composite Construction essentially the same as that of the floor panel 3@ previously described; whereby 'the end panel %ti includes the outer plyweod sheet 81, the inner plywood sheet 32 and the intermediate slab 83 of foarned polystyrene. The end panel %is arranged adjacent to the right-hand end wall 41, as shown in FG. 3, and comprises a pluralty of sections suitably secured together; the end panel 919 being of composite construction essentially the same as that of the floor panel 39 previously described; whereby the end panel 911 includes the outer plywood sheet 91, the inuer plywood sheet 92 and the intermediate slab 93 of toamed polystyrene. The ceiling panel is arranged below the roof 42, as shown in FlGS. 3 and 4, and comprises a plurality of sections suitably secured together; the celing panel 16@ being of composite Construction essentially the same as that of the floor panel 313, previously described; whereby the ceiling panel 19@ includes the outer plywood sheet 191, the inner plywood sheet 1%@ and the intermediate slab 1113 of foaned polystyrene.

Referring now more particularly to FlGS. 2, 3 and 4, it will be appreciated that the composite heat-insulating liner tha-t is housed in the car body comprises the six individual heat-insulating panels 39, 79, 75, se, 911` and 11th' that constitute the boundary wall structure ot the lading compartment 61. In the arrangement, the lower ends of the side panels 719 and 75 are supported directly upon the adjacent marginal sides of the floor panel 3%, the lower ends of the end panels liti' and %ti are supported directly upon the adjacent marginal ends of the floor panel 31 the opposite sides of the ceiling panel 11%@ respectively partially overlap the respective upper ends ot the side panels 7@ and 75 (as shown in FG. 4), and the oppcsite ende of the ceiling panel 1 3@ respectively fully overlap the respective upper ends of the end panels 819 and 9@ (as shown in FIG. 3). Also a doorway is provided through the side panel "70` and the adjacent side wall iti; which doorway is suitably framed, as indicated at 74 in FIG. 2; likewise a doorway is provided through the side panel 75 and the adjacent side wall 411; which doorway is suitably framed, as indicated at '79 in FG. 2. The doorways 74 and 79` are provided with cooperating heat-insulating doors, in the usual manner; the door 11 15 cooperating with the doorway 74 being indicated at FIG. 1 as supported upon cocperating upper and lower guides 1196 and 107.

The side panels 713' and '71 are securely fastened to the respective side walls {ti of the car body; and as best illustrated in FIG. 14, the side panel '751 may be Secured to the adjacent side wall 4 of the car body at each of the upstanding outside posts 43 utilizing a number of "Huck" bolts, or ;other blind fasteners 4301. In the arrangement, the outside post 43 is substantially U-shaped in lateral cross-section including a pair of outwardly directed flanges 43' that are directly Secured in plaee with' respect to the side wall i@ by the faste ners 4361; which fasteners dita also secure in place the outside sheet '71 of the adjacent side panel 76. Specifically, two cylindrical cores 74 may be cut from the composite Construction of the side panel 7@ in alignment with the two fasteners dita and removed from the side panel 711 prior to the setting of the fasteners %a firmly in position, so that the fasteners 7351 secure in place the outside post 43, the side walls it) of the car body and theoutside plywood sheet '71 of the adjacent side panel '70. After setting of the fasteners 43 the cores 7 1 may be again coated with a suitable glue or cement and then-reinserted into the holes provided through the styrofoam slab 73 and through the inner plywood sheet 72, thereby again to provide unbroken heat-insulation through the side panel 711 between the plywood sheets '71 and 72, so as to minimize heat flow from the exterior through the side panel '70 into the lading compartment 61.

As previously noted, the opposite sides of the ceiling panel 15311 only partially overlap the upper ends of the respective side panels '70 and '75, thereby providing voids between the side walls 40 and the opposte sides of the ceiling panel 1190 adjacent to the junctions of the side Walls iti and the opposite sides of the root sheet 42. As llustrated in FIG. 4, these Voids are filled with insulating material; and specifically, the void mentioned defined adjacent to the junction of the side of the ceiling panel 1136 and the upper end of the side panel 7@ is filled by a longitudinally extending' preformed block 11@ of `foamed polystyrene and a mass 111 of foamed-in-place polyurethane'. in producng the assembly, as shown in FlG. 4, the ceiling panel 113@ is secured in place by a series of longitudinally spaced-apart brack ets 112 carried by the upper portion of the Z-shaped Construction 44 provided at the upper end of the adjacent side wall 4%; which brackets 112 project inwardly over the ceil ing panel 1111) and clamp the samesecurely in place. The preformed block 110 is arranged as a flller block upon the upper end of the side panel 7%; and the space between the filler block 11@ and the adjacent side of the ceiling panel 1% is filled with the mass 111 of foamed polyurethane. More particularly, the polyurethane material mentioned may be foarned in place as the last step in producing the assembly, and after the filler block 11@ is positioned upon the upper end of the side panel 70 and after the brackets 112 have been Secured in place to position the ceiling panel 1 39. Furthermore, two layers 113 and 114 of fibrous insulating material, such as glass fibers, are arranged upon the top of th ceiling panel 1011 and in the space between the ceiling panel 1% and the root' sheet 42, thereby substantially to fill this void and further to insulate the lading compartment 61 against the entry of heat thereinto through the roof sheet 12. i

Again reverting to the Construction of the end panels and 9% and referring to FIGS. 2 and 3, it is pointed out that these panels incorporate additional structure that is not necessary in theconstruction of the side panels '713 and '75. Specifically, lower and upper beams 121 and 122 are respectively incorporated in the lower and the upper ends of the end panel 80, which beams 121 and 122 may be formed of cak or other strong Wood. The lower bearn 121 is positioned between the outer and inner plywood sheets 81 and 82 and below the slab 83 of foarned polystyrene and located immediately in contact with the adjaoent upper surface of the floor panel 311; lkewse, the upper beam 122 is positioned between the outer and inner plywood sheets 81 and 82 and above the slab 83 of foamed polystyrene and located somewhat below the adjacent lower surface of the ceiling panel 18th. In the arrangernent, the space between the plywood sheets 81 and %2 disposed above the upper beam 122 and below the adjacent lower surface of the ceiling panel 1% is filled with another slab of foamed polystyrene 83', thereby completing the assembly of the end panel 80. The Construction of the end panel 9@ ,is identical to that of the end panel 36; whereby the end panel 9@ comprises the lower and upper beams 131 and 132, as well as the slabs 93 and 93' of foamed polystyrene, all arranged between the outer 'and inner plywood sheets 91 and 92. In passing, it is mentioned that the lower beams 121 and 131 respectively incorporated in the end panels 315 and 91) are disposed in a common horizontal plane positioned immediately above the floor panel 39. Similarly, the upper beams 122 and 132 respectively incorporated in the end panels 80 and are disposed in a common horizontal plane positioned somewhat below the ceiling panel 1%.

As best shown in FIGS. '2 and 4, a longitudinally eX- tending lower center securing sill 149 is arranged within the lading compartment 61 and directly Secured to the main floor 34 and extending between the end panels &ti and 919. Also, two longitudinally extending and laterally spaced-apart lower side securing sills 141 and 142 are arranged within the lading compartment 61 and directly secured to the main floor 34 and extending between the end panels 80 and 90. In the arrangernent, the lower center securing sill 140 is disposed substantially centrally of the main floor 34, while the lower side securing sills 141 and 142 are disposed respectively adjacent to the opposite sides of the main floor 34 and respectively adjacent to the side panels 70 and 75. Moreover, the upper surfaces of the lower securing sills 140, 141 and 142 are disposed substantially in the plane of the lading floor 36 so as to define a generally unbroken work floor within the lading compartment 61. As illustrated in FIG. 2, a lower center stub sill 150 is arranged upon the floor of the machinery compartnent 62 in alignment with the center securing sill 140 and extending between the end panel 80 and the adjacent left-hand end wall 41 of the car body Similarly, two lower side stub sills 151 and 152 are arranged upon the floor of the machinery compartment 62 respectively in alignment with the lower side securng sills 141 and 142 and extending between the end panel 80 and the adjacent left-hand end wall 41 of the car body.

As best shown in FIGS. 2, 5, 6, 7 and 8, a laterally extending lower keeper beam 161 fabricated of steel is arranged adjacent to the exterior surface of the end panel 90 and located in one of the deep corrugations formed in the lower portion of the adjacent right-hand end wall 41 of the car body; which lower keeper beam 161 is disposed in alignment with the lower beam 131 incorporated in the end panel 90. More particularly, the lower keeper beam 161 is positioned between the end panel 90 and the adjacent end wall 41 and is rigidly fastened to the adjacent right-hand ends of the securing sills 140, 141 and 142. Specifically, the central portion of the lower keeper beam 161 is secured to a flange 170 carried on the right-hand end of the lower center securing sill 140 by a series of bolts 170'; one end portion of the lower keeper beam 161 is secured to a flange 171 carried on the right-hand end of the lower side securing sill 141 by a series of bolts 171'; and the other end of the lower keeper beam 161 is secured to a flange 172 carried on the right-hand end of the lower side securing sill 142 by a series of bolts 172'. In the arrangement, the bolts 170', 171' and 172' are preferably formed of stainless steel in order to minimize the conducton of heat from the lower keeper beam 161 into the lading chamber 61. The opposite ends of the lower keeper beam 161 are rigidly anchored to the corner posts 50 and 51 at the right-hand end of the car body by the previously mentioned bolts 52. As illustrated in FIG. 2, a lower keeper beam 162 is provided at the left-hand end of the car body inwardly of the adjacent end wall 41 and rigidly secured to the adjacent left-hand ends of the lower stub sills 150, 151 and 152; and the opposite ends of the lower keeper beam 162 are rigidly anchored to the adjacent corner post structures 50 and 51 at the left-hand end of the car body. The left-hand ends of the securing sills 140, 141 and 142 are rigidly secured to the right-hand ends of the adjacent stub sills 150, 151 and 152 by associated bolts 170", 171" and 172", which last-mentioned bolts are also preferably formed of stainless steel to prevent the transfer of heat therethrough from the machinery compartment 62 into the lading compartment 61.

In view of the foregoing description, it will be understood that the lower keeper heam 161 is rigidly secured to the two adjacent corner constructions at the right-hand end of the car body; and likewise, the lower keeper beam 162 is rigidly secured to the two adjacent corner Constructions at the left-hand end of the car body. The righthand ends of the lower securing sills 140, 141 and 142 are rigidly secured to the lower keeper beam 161 through the lower beam 141 incorporated in the adjacent end panel 90; the left-hand ends of the lower securing sills 140, 141 and 142 are rigidly secured to the right-hand ends of the lower stub sills 150, 151 and 152 through the lower beam 121 incorporated in the adjacent end panel and the left-hand ends of the lower stub sills 150, 151 and 152 are rigidly secured to the adjacent lower keeper beam 162. Thus, it will be understood that any longitudinal shocks applied to the lower securing sills 140, 141 and 142 will be transmitted to the lower keeper beam 161 through the lower beam 131 ncorporated in the adjacent end panel 90, without damage thereto; and likewise, the longitudinal shocks applied to the lower securing sills 140, 141 and 142 will be transmitted to the lower stub sills 150, 151 and 152 through the lower beam 121 incorporated in the adjacent end panel 89, without damage thereto. Of course, the longitudinal shocks applied to the lower stub sills 150, 151 and 152 are transmitted directly to the adjacent lower keeper beam 162. Thus the longitudinal shocks appled to the lower securing sills 140, 141 and 142 are transmitted through the end panels 80 and 90, without damage thereto, to the lower keeper beams 161 and 162 and thence to the four corner post constructions provided in the car body.

As best shown in FIGS. 2, 3 and 4, a flue arrangement is provided about the boundary of the lading compartment 61 by a plurality of flue sheets, including a pair of side flue sheets 131 and 102, a pair of end flue sheets 183 and 184 and a ceiling flue sheet 185. More particularly, the end flue sheet 103 is arranged in upstanding position and spaced inwardly with respect to the adjacent end panel 80 so as to define an upstanding evaporator chamher 186 therebetween, the lower end of the end flue sheet 183 being supported upon the adjacent left-hand ends of the I-beams 35 carrying the lading floor 36; the end flue sheet 184 is arranged in upstandng position and spaced inwardly with respect to the adjacent end panel so as to define on upstanding flue 187 therebetween; the side flue sheet 181 is arranged in upstanding position and spaced inwardly with respect to the adjacent side panel '70 so as to define a flue 188 therebetween; and the side flue sheet 182 is arranged in upstanding position and spaced inwardly with respect to the adjacent side panel 75 so as to define a flue 189 therebetween. The ceiling flue sheet 185 is arranged in a horizontal position and spaced below the adjacent ceiling panel so as to define a flue 190 therebetween. The upper portion of the evaporator chamber 186 communicates with the adjacent ends of the flues 188, 189 and 190; and the lower portion of the evaporator chamber 186 communicates with the ad jacent ends of the flues 188 and 189 and also with the space disposed between the main floor 34 and the lading floor 36. The sides of the flue 190 communicate with the respective upper portions of the flues 188 and 189; the right-hand end of the flue 190 communicates with the top of the flue 187; and the right-hand ends of the flues and 189 communicate with the respective sides of the flues 187. Finally, the lower end of the flue 187 communicates with the lading compartment 61 and also with the space between the main floor 34 and the lading floor 36.

An upstanding refrigerant evaporator 191 is arranged in the evaporator chamber 186; and disposed below the refrigerant evaporator 191 is a circulating fan 192 that is driven by an associated electric motor 193, the fan 192 being arranged in suitable baflle structure, indicated at 194, arranged in the lower portion of the evaporator chamber 186. Accordingly, it will be understood that operation of the electric motor 193 eflects operation of the fan 192 and the consequent circulation of a stream of air upwardly through the evaporator chamber 186 and fundamentally into the flue 190. 'From the flue 190, the air circulates into the tops of the flues 188 and 189 and 187; from the bottoms of the flues 188 and 189, the air circulates downwardly into the space between the main floor 34 and the lading floor 36; and from the bottom of the flue 187, the air circulates into the lading compartment 61 and thence through the lading floor 36 into the shown in the interest of Simplicity. Of course, the refrigerating machine also includes the refrigerant evaporator 191 wherein liquified refrigerant is expanded effecting cooling thereof and the consequent cooling of the air that is circulated by the fan 192 over and through the refrigerant evaporator 191. Accordingly, the circulated air is cooled by the refrigerant evaporator 191 and effects corresponding cooling of the lading compartment 61, and of course, the lading arranged therein.

Preferably the side fiue sheets 11,`12, 183 and 134 are forned of plywood; and as illustrated in FIG, 14,

the side flue sheet 131 is Secured in place inwardly by the adjacent panel 70 by a series of upstanding longitu dinally spaced-apart posts 191 arranged between the side flue sheet 181 and the adjacent inner plywood sheet '12 of the side panel 711. As illustrated, the post 191 is generally channel-shaped and defines the space between the sheet '72 and 181; thereby definng the side fine 183. In the arrangement, the post 191 is provided with a pair of oppositely directed fianges 192 that may be securely fastened to the adjacent inner plywood sheet 72 by Huck bolts 193, or other suitable blind fasteners, the blind fas- V teners 193 extending only through the adjacent inner plywood sheet 72. The central portion of the posts 191 may be suitably Secured to the side fiue sheet 131 by a series of screws 194 arranged in corresponding recesses 195 provided in the inner surface of the side lue sheet 181, the shank of each screw 194 extending through an associated hole provided in the side flue sheet 181 and being received in a threaded hole provided in the central portion of the post 191. i

Preferably the ceiling flue sheet 185 consists essentially of a sheet of aluminum and is Secured in place by an arrangement including a series of laterally extending and longitudinally spaced-apart rafters 261 arranged thereabove and suitably secured thereto, as shown in FIGS. 3 and 4. More particularly, the rafters 201 are positioned above the ceiling flue sheet 185 and exteriorly of the lading compartment 61 and eXtend laterally through the flue 1%, the opposite ends of each of the rafters 21 1 being received by a pair of fixtures 2112 carried by the upper ends of a pair of the posts 191. Accordingly, it will be understood that the series of laterally extending and longitu-v dinally spaced-apart rafters 2111 are supported by the longitudinally spaced-apart series of pairs of upstanding posts 191; and in turn, the ceiling flue sheet 185 is suitably Secured to the lower surfaces of the rafters 2111.

As best shown in FIGS. 4, 9, lO and 11, there is arranged within the top of the lading compartnent 61 and below the ceiling fiue sheet 185, a longitudinally exterding upper center securing sill 2111 and two longitudinally extending upper side securing sills 211 and 212; which upper securing sills .210,211 and 212' are respectively disposed directly above the corresponding lower securing sills 140, 141 and 142; and which upper securing sills 210, 211 and 212 are respectively arranged in the upper plane of the beams 122 and 132 respectively incorporated in the end panels 80 and 90.

As best shown in FIGS. 9, and ll, a laterally eX- tending upper keeper beam 221 fabricated of steel is arranged adjacent to the exterior surface of the end panel 96 and located in one of the deep corrugations forned in the upper portion of the adjacent right-hand end wall 41 of the car body; which upper keeper beam 221 is disposed in alignment with the upper beam 132 incorporated in the end panel 911. More specifically, the upper keeper bearn 221 is positioned between the end panel and the adjacent end wall 41 and is rigidly fastened to the adjacent right-hand ends of the securing sills 210, 211 and 212. Specifically, the centralportion of the upper keeper beam 221 is securedto a ange 213 carried on therighthand end of the upper center securing sill 218 by a series I of bolts 213' that are preferably made of stainless steel, as previously explained. In the arrangement, the upper keeper beam 221 corresponds to the lower keeper beam 161 previously described in detail; whereby it will be understood that the right-hand ends of the upper side securing sills 211 and 212 are likewise rigidly secured thereto; and noreover, the opposite endsof the upper keeper beam 221 are rigidly Secured to the corner constructions of the right-hand end of the car body in a manner similar to that of the lower keeper beam 161.

Furthermore, it will be understood that an upper keeper beam 222, not shown, is also provided at the left-hand end of the car body and disposed directly above the lower keeper beam 162, just as the upper keeper beam 221 is arranged at' the right-hand end of the car body and disposed above the lower keeper beam 161. This upper keeper beam 222, not shown, arranged at the left-hand end of the car body is rigidly secured to the upper portions of the corner constructions at the left-hand end of the car body and is further Secured to the left-hand ends of the upper stub sills, not shown, provided in the machinery compartnent 62; and the right-hand ends of the upper stub sills, not` shown, are rigidly Secured to the left-hand ends of the upper securing silis 219, 211 and 212 through the adjacent end panel 811. In other words, the arrangement of the upper securing sills 213, 211 and 212 With respect to the end panels St) and 9@ and with respect to the two upper keeper beans 221 and 222 is altogether commensurate with that of the arrangement of the lower` securing sills 140, 141 and 142 described in detail heretofore.

Accordingly, it will be understood that longitudinal shocks applied to the ilpper securing sills 210, 211 and 2 12 are transmtted to the upper keeper beams 221 and 222 and thence to the corner Construction at the opposite ends of the car body, without damage to'the end panele` 30 and 96, by virtue of the incorporation of the upper beams 122 and 132 in the respective end panels sa and 90. A series of partitiohs or load dividers 231 are arranged in the lower half of the lading compartrnent 61 and a series of partitions or load dividers 232 are arranged in the upper half of the lading conpartment 61, both as viewed in FIG. 2. The load dividers 231 eXtend laterally from and adjacent to the side fiue sheet 181 toward the center of the lading compartrnent 61 and are rnounted for longitudinal rolling movements upon the upper securing rails 210 and 211, while the load dividers 232 extend laterally from the adjacent side flue sheet 182 toward the center of the lading compartrnent 61 and :are mounted for longitudinal rolling movements upon the upper securing rails 210 and 212. Preferably, each of the load dividers 231 and 232 is of the Construction available commercially as Equipco load divider and essentially comprises an upstanding hollow panel provided with rollers 233 carried adjacent to the uppercorners thereof and arranged in rolling engagernents with corresponding longitudirally extending trackways respectively provided by the upper securing sills 210 and 211 or 210 and 212. Also each of the panels or load dividers 231 carries two locks 241 and 242 at the upper corners thereof and two locks 243 and 244 at the lower corners thereof, as well as an Operating handle 245' associatedwith mechanisms, indicated by the broken lines 246, 247, 248 and 249, and interconnectng the respective locks 241, 242, 243 and 244. As illustrated in FIG. 4, the handle 245 occupies its locked position so that the mechanisrns 245, 247, 243 and 249 are operated to move the locks 241, 242, 243 and 244 outwardly into their locked positions With respect to the sills 211, 210, 141 and 1411, respectively. Specifically, each of the sills 211, 210, 141 and 140 is provided with a longitudinally spaced-apart series of holes therein that are adapted to cooperate with the corresponding one of the locks 241, 242, 243 and 244. Accordingly, as viewed in FIG. 4, the locks 241, etc., occupy their locked positions with respect to the sills 211, etc.; whereby the longitudinally adjusted position of the load divider 231 is securely established.

In View of the above description of the Construction and arrangement of the load divider 231, it will be understood that when the handle 245 is operated into its unlocked position, the locks 241, etc., are withdrawn from the holes provided in the sills 211, eto; whereby the load divider 231 may be rolled longitudinally upon the rollers 244 in engagement with the trackways provided by the upper securing sills 211 and 210. Specifically, the load divider 231 may be rolled longitudinally along the upper securing sills 210 and 211 into a desired longitudinal location within the lading compartment 61; whereupon the handle 245 may be operated into its locked position; whereby the load divider 231 in its longitudinally adjusted position is securely locked to the four securing sills 140, 141, 210 and 211, as previously explained.

In view of the foregoing description of the Construction and arrangement of the load divider 231, it will be understood that the series of load dividers 231 and the series of load dividers 232 may be independently adjusted indivdually within the lading compartment 61 for the purpose of sectionalizing or subdividing the lading arranged in the lading compartment 61 into corrcsponding sections in order to prevent the transmission of shocks between the different sections of the lading and in order securely to maintain the sections of the lading in their respectively supported positions within the lading compartment 61. Also, it will be understood that when the load dividers 231 and 232 are properly adjusted and secured in place with respect to the securng sills 140, 141, 142, 210, 211 and 212, all of the longitudinal shocks are transmitted directly from the sections of the lading to the various load dividers 231 and 232, and thence via the securing sills 140, 141, 142, 210, 211 and 212 to the keeper beams 161, 162, 221 and 222, and thence to the four corner constructions of the car body, without damage to the heatinsulating end panels 80 and 90, by virtue of the incorpo- Iation of the solid beams 121 and 122 in the end panel 80 and the incorporation of the solid beams 131 and 132 in the end panel 90, as previously explained.
